Wish granted, the person I let used my account will disappear, while I remain and can crush your wishes as I please. Bwhahaha! (and if that doesn't work, a robot crushed your wish and that isn't a who, it's a what, so your wish failed because of technicalities.) 

I wish for nothing in this specific in this instance to occur or have any strange changes to happen throughout the whole universe. (Because I don't need a wish. ;D)
